The nebula begins to spin and flatten.

None of the above

Detailed explanation-1: -The center of the nebula begins to get hot and dense. Gravity causes light gases to move to the center while heavier materials and ice stay in outer areas. A protostar forms in the center of the nebula. Gravity causes light gases to move to the center while heavier materials and ice stay in outer areas.
Detailed explanation-2: -The steps to nebular theory go as follows. Nebula becomes a solar nebula as a region within the cloud of gas and dust condenses into a core and forms a protostar. The condensing material could have been caused by a nearby supernova shockwave. The material surrounding the protostar collapses into an accretion disk.
Detailed explanation-3: -The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun which clumped up together to form the planets.
Detailed explanation-4: -step one(4)-The solar nebula consisted of.-hydrogen, step two(2)-A disturbance.-caused the solar nebula to slowly contract and rotate. step three(2)-The solar nebula assumed a flat, disk shape. step four(2)-Inner planets began to form from metallic. step five(2)-Larger outer planets began forming from fragments.
